forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view that shows how the adjustable curtain supports are de tachably connected with the main standard of the complete apparatus and curtains on rollers adjustably connected with the curtain supports as required for practical use.

' Fig. 2 is an enlarged transverse sectional view on the line as 90 of Fig. 1 and shows how the curtain rollers are pivotally'connected with the lower curtain support so that they can be extended at different angles relative to the adjustable support and the standard. Fig. 3 is a top view that shows how curtain roller carriers are slidably and pivotally connected with the adjustable roller su ports to be moved to and from the standar and extended therefrom at various degrees of an gles at different times as required for focusing light upon a person before a camera advantageously. Fig. 4 is an enlarged view of a pulley on the upper rollersupport and shows how the pulley is slidably and rotatably connected therewith and provided with means for fastening a cord to the pulley as required for retaining the curtain elevated to different heights at different times.

The numeral 10 designates a portable base to which is fixed, preferably detachably, a tubular standard 12 and in the upper end is an adjustable extension 13.

A bearer 14 is slidably, adjustably and detachably connected with the standard 12 and fastened thereto at any point of elevation desired by means of a set screw 15 as shown in Fig. 1, or in any suitable way. A corresponding bearer 16 is connected in the same way with the upper end portion of the standard 12.

To [lower bearer 14 is fixed a cross bar 17 for supporting a roller carrier 18 on each of its end portions. Only one of said carriers is shown in Fig. 1 and consists of a straight length of sheet metal that is stiffened by upturned flanges 19 at its sides and bearings 20 at its ends for the journals on the ends of curtain rollers 21.

The roller carriers, 18, have longitudinal slots 22 in their centers and over the slots are placed flat pieces of sheet metal, 23, and bolts 24 extended down through all the overlying parts, as shown in Fig. 2, to pivotally and slidably connect them in such a manner that the carriers and curtains 25 on the rollers 21 can be readily moved towards the standard 12 or away from it and also set at any angle desired relative to the standard as required for regulating the transmission of light between the curtains to a person or persons or object before a camera. A nut 26 on the lower end of the bolt 24 retains it in place.

To the upper bearer 16 is fixed a rod 27 and on the rod is a pulley 28slidably and rotatably mounted thereon and the curtain 25 is connected with the pulley by a cord 29, as shown in Fig. 1 in such a manner that the curtain can be raised and lowered by simply rotating the pulley as required to lengthen and shorten it between the pulley and the curtain and by sliding the pulley on the rod 27 the cord can be readily placed in perpendicular alinement with the bolt 24 and the center of the curtain 25.

The pulley 28 has an integral extension 30 and a thumb screw 31 seated in the extension for locking the pulley fast on the rod 27 at any point desired for retaining the curtain, 25, at any point of elevation desired.

Having thus set forth the purposes of my invention and its construction and manner of use the practical operation and utility thereof is obvious.

What I claim as new and desire to secure by Letters-Patent, is:

1. In a photographers light regulator, a standard fixed to a base, a bearer slidably connected with the standard, a cross bar fixed to said bearer and a roller carrier pivotally and slidably connected with the cross bar fixed to said bearer, to operate as set forth.

In a photographers light regulator, a standard fixed to a base, a bearer slidably connected with the standard, a cross bar fixed to said bearer, a roller carrier pivotally and slidably connected with the'cross bar fixed to said bearer, a longitudinal slot in the roller carrier and a pivotal bolt extended through the slot and the cross bar, to operate as set forth.

3. In a photographers light regulator, a standard fixed to a base, a bearer slidably connected with the standard, a cross bar fixed to said bearer, a roller carrier pivotally and slidably connected with the cross bar fixed to said bearer, a longitudinal slot in the roller carrier, a pivotal bolt extended through the slot and the cross bar, roller bearings at the ends of the roller carrier and a curtain roller mounted in said bearings, to operate as set forth.

4. In a photographers light regulator, a standard fixed to a base, a bearer slidably connected with the standard, a cross bar fixed to said bearer, a roller carrier pivotally and slidably connected with the cross bar fixed to said bearer, a longitudinal slot in the roller carrier, a pivotal bolt extended through the slot and the cross bar, roller bearings at the ends of the roller carrier, a curtain roller mounted in said bearings, a curtain fixed to the roller and means to elevate and suspend the curtain at different points of elevation, to operate as set forth.

5. In a photographers light regulator, a standard fixed to a base, a bearer slidably connected with a cross bar fixed to said bearer, a roller carrier pivotally and slidably connected with the cross bar fixed to said bearer, a longitudinal slot in the roller carrier, a pivotal bolt extended through the slot and the cross bar, roller bearings at the ends of the roller carrier, a curtain roller mounted in said bearings, a curtain fixed to the roller, a rod fixed to the up er end portion of the standard, a ulley sfidably and rotatably mounted on t e rod to elevate and suspend the curtain at different points of elevation, to operate as set forth.

6. In a photographers light regulator, a standard fixed to a base, a bearer slidably connected with the standard, a cross bar fixed to said bearer, a roller carrier pivotally and slidabl connected with the cross bar fixed to saic bearer, a bearer adjustably connected with the up er end portion of the standard and a rod xed to the bearer to extend horizontally, to operate as set forth.

7. In a photographers light regulator, a standard fixed to a base, a bearer slidably connected with the standard, a cross bar fixed to said bearer, a roller carrier pivotally and slidably connected with the cross bar fixed to said bearer, a bearer adjustably connected with the up er end portion of the standard, a rod fixed to the bearer to extend horizontally, a pulley slidably and rotatably mounted on the rod and means to fasten the pulley to the rod, to operate as set forth.
